U.S. Aims For International Support In Action Against Syria

Secretary of State Kerry has pronounced an all-but-final U.S. verdict against the Syrian government for suspected use of chemical weapons in an "indiscriminate slaughter" of civilians. U.S. warships are within missile range, and U.S. envoys are talking to allies to see what kind of action they might support. David Greene talks to Frederic Hof, who was a special State Department adviser on Syria for the Obama administration. He is now a senior fellow at the Atlantic Council.
